Abstract
A circuit is provided that includes a castellated channel device that comprises a heterostructure overlying a substrate structure, a castellated channel device area formed in the heterostructure that defines a plurality of ridge channels interleaved between a plurality of trenches, and a three-sided castellated conductive gate contact that extends across the castellated channel device area. The three-sided gate contact substantially surrounds each ridge channel around their tops and their sides to overlap a channel interface of heterostructure of each of the plurality of ridge channels. The three-sided castellated conductive gate contact extends along at least a portion of a length of each ridge channel.
